Definitions
- the present invention relates to a refrigeration system of a refrigerator, particularly a domestic refrigerator with a refrigeration compartment and a freezer, as well as a process for operating the system.
- the present invention also relates to the fluid compressor suction system belonging to the disclosed cooling system.
- a refrigeration system basically comprises a compressor, a condenser, an expansion device and an evaporator.
- the refrigerant in the gas phase
- the refrigerant is compressed in the compressor and flows into the condenser, where it is cooled, for example, by ambient air, and passes into the liquid phase.
- High pressure refrigerant flows to the expansion device, where its pressure is reduced, and then flows to the evaporator, where it absorbs heat from the charge (food, for example) and into the gas phase.
- the refrigerant is aspirated by the compressor, thus completing the refrigeration cycle.
- the most commonly used refrigeration system comprises a compressor and a condenser, from which a line of refrigerant to the freezer evaporator departs, and then that line passes through the evaporator of the refrigeration compartment and returns to the compressor.
- the system described above has a lower cost, however it is low efficiency as it operates at the lowest temperature, ie the freezer temperature.
- This type of suction system allows a single compressor with a single suction inlet to work at two different pressures. This also allows the compressor "C” to operate at high and low pressure in alternating cycles, optimizing its energy coefficient (compared to other arrangements pertaining to the current state of the art).

- the housing is at the same pressure as the suction and in the case of compressors that use lubricating oil for their bearings, it can easily return to the crankcase.
- one of the suction lines can be chosen to be equalized with the interior of the casing and also allow oil coming in this line to return to the crankcase. Oil returning from the unequal line will be pumped back to the discharge line, where it will mix with the gas coming from the other suction line and a part will be taken to the crankcase when it returns to the compressor via the equalized suction line. This way there will always be a way for the oil to return to the compressor.
